Sorry, but that's wrong. It's the ratio between the size reserved for newly allocated objects (New Generation) and that used for long-lived objects (Tenured or Old Generation). It has nothing to do with space for Permanent Generation objects, which are primarily instances of java.lang.Class. Eden space is a portion of the NewGen space reserved just for object creations; the rest of NewGen space is split into two "survivor" spaces. Normal objects migrate from Eden to survivor to Tenured as a result of GC action. GC of the PermGen area is largely independent of GC activity on the other generations, other than using references from normal objects (among other roots) to determine which PermGen objects must be retained. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
